Abnormal Bleeding Three Months Post-Miscarriage: Causes and Concerns

Abnormal bleeding three months after a miscarriage?

Hello Doctor, my child was diagnosed with a neural tube defect at 12 weeks, and therefore I underwent a therapeutic abortion on December 5th of last year.
After the abortion, I had two menstrual periods (the first on January 15th and the second on February 17th).
Before each period, I experienced a small amount of spotting, and then the full flow would start a day or two later.
Both times, the flow was very heavy.
However, on March 8th, I suddenly started experiencing intermittent bleeding, with varying amounts of flow.
This continued until March 24th, when the bleeding increased suddenly, and I began to pass some substances that resembled blood clots but were not clearly identifiable.
This has continued until today.
I have seen a gynecologist, who performed an ultrasound and found no issues.
I was prescribed medication to promote uterine contractions and hemostatic agents, but after three days, there has been no change.
I would like to ask if this is normal, what could be the possible reasons, and whether I should undergo further examinations? What should I do?

More Info

Abnormal bleeding following a miscarriage can be concerning, especially when it persists for an extended period, as you've described. After a miscarriage, it is not uncommon for women to experience irregular bleeding or changes in their menstrual cycle. However, the situation you are experiencing—prolonged bleeding with varying intensity and the presence of clots—warrants further investigation.

Firstly, it is essential to understand that after a miscarriage, the body undergoes significant hormonal and physical changes as it returns to its pre-pregnancy state. This process can sometimes lead to irregular bleeding patterns. However, the fact that you have experienced bleeding for several weeks, especially with the presence of clots, raises some concerns that should be addressed.

There are several potential causes for your symptoms:
1. Retained Products of Conception: After a miscarriage, some tissue may remain in the uterus, which can lead to continued bleeding. This retained tissue can cause the uterus to contract irregularly, leading to intermittent bleeding and the passage of clots.

2. Hormonal Imbalance: The hormonal fluctuations following a miscarriage can lead to irregular menstrual cycles. If your hormone levels, particularly progesterone and estrogen, are not returning to normal, this can result in abnormal bleeding.

3. Uterine Infections: An infection in the uterus (endometritis) can occur after a miscarriage, leading to prolonged bleeding, pain, and sometimes fever. This condition requires prompt medical treatment.

4. Other Gynecological Issues: Conditions such as fibroids, polyps, or other structural abnormalities in the uterus can also lead to abnormal bleeding.

Given your situation, it is advisable to seek further evaluation from a healthcare provider, preferably a gynecologist. You should discuss your symptoms in detail, including the duration and nature of the bleeding, any associated pain, and the presence of clots. A thorough examination, including a pelvic exam and possibly a repeat ultrasound, may be necessary to rule out retained tissue or other complications.

In addition to imaging studies, your doctor may also consider blood tests to assess your hormone levels and check for any signs of infection. If retained products of conception are confirmed, a procedure such as dilation and curettage (D&C) may be necessary to remove the remaining tissue and help your body heal properly.

While it is understandable to feel anxious about these symptoms, it is crucial to address them with your healthcare provider. They can provide you with the appropriate guidance and treatment options based on your specific situation.
In the meantime, monitor your symptoms closely. If you experience severe pain, fever, or an increase in bleeding, seek immediate medical attention. It is essential to prioritize your health and well-being during this time, as your body needs to recover fully from the miscarriage.

In summary, while some irregular bleeding can be normal after a miscarriage, the duration and nature of your symptoms suggest that further evaluation is necessary. Do not hesitate to reach out to your healthcare provider for a comprehensive assessment and appropriate management.
